For the reaction of one mole of zinc dust with one mole of sulphuric acid in a bomb calorimeter, `Delta U and w` corresponds to

A

`Delta U lt 0, w=0`

B

`Delta U lt 0, w lt 0`

C

`Delta U gt 0, w=0`

D

`Delta U gt w gt 0`

Text Solution

Verified by Experts

The correct Answer is:
A
`Zn+H_(2)SO_(4)rarr ZnSO_(4)+H_(2)`. It is an exothermic reaction so `Delta U lt O`. In Bomb calorimeter the process occurs at constant volume so w = 0.
